To all whom 'it may concern: .4,

\Be it known that l, JonNA L. Hanni', a citizen of the United States, residing in the city of Los Angeles, county of Los Angeles, and Sta-te of California, have invented new and useful. Improvements in Hydrocarbon- Burners, of which the followingis a spec1- draft conditions of the flues and without the use of expansible fluid pressure such steain or compressed air. I accomplish this object by means of the burner described herein and illustrated inthe accolnpanying` drawings in which:

lFigure l is a longitudinal central vertical sectionfof a heating furnace equipped with my improved burner. Fig. 2 is a plan of the burner detached, with parts broken away for clear-ness of illustration.

In the drawings 5 is the outside casing of a hot air furnace which is supplied with a cold air pipe 6 entering the bottoni thereof. 7 are the service pipes opening from the top of the outer casing andV leading the hot air to the place ofuse.

8 is the casing of the combustion chamber 9, and l0 is the draft pipe opening from. the combustion chamber and leading to the chimney. l i

1l are the ordinary grate bars in the hottom of the combustion chamber.

' My burner is preferably placed upon the rate bars of the furnace or kitchen range as y illustrated in' Fig.4 l;

The burner consists of the bedplate l2 which for a circular furnace would preferably be circular in shape as shown in the drawings. I prefer tohave the bed plate supported by an annular ring 123 as the space laround the burner must. be closed 'by brick Work 14 so'as to/ciuseall the an' entering the combustion chamber to pass through the burner, and by usin the supporting ring the base plate is hfte above the brick work,

.but if desiredihe base plate could be placed directly upon the grate bars and the supporting ring omitted. Adjacent tov the Outer edge thereof the base plate is provided with draft openings or ports 15. Ad jacent to and within the' line of draft ports an annular trough 1G, the sides of which i slope upwardly and outwardly to the draft ports and upwardly and inwardly to near the center of thebed plate. I In the center of the bed plate is an aperture 17 which is internally threaded for the reception of the upper end of the liquid fuel supply pipe 18 which is preferably screwed intosaid opening. lf desired, however, the threads inav be omitted and the parts'slightly tapered t'o malte a tight tit.4 Upon the top of the base plate and surrounding and inclosingl the draft ports is the hood ordraft directing plate i9, which curves upwardly and inwardly and then downwardly and inwardly and terminating with a draft openingr 2() in the center thereof. A spreader plat-e 2l having legs 22 rests upon thelcentral portion of the buse plate. The legs of this spreader plate straddle the top of the supply pipe which projects slightly above the top of the bed plate so as to lkeep the spreader plate centrally alined upon the hed plate, This spreader plate is circular and spreader stands whereA it projects over theA hood is controlled somewhat by the draft of the chimney. For an ordinary furnace burner l have found. the following dimensions produce satisfactory results. A bed plate twelve inches in diameter, with draft openings about seven eighths of an inch in width. The trough in the bed plate is about one inch deep. 'lhe hood is about eleven and one half inches in diameter and the aperture through the hood about four and one half inches in diameter. The top of the spreader is about six inches in diameter and about two inches high. The draft channel between the spreader and hood is about one inch, the supporting ring for the bed plate is about eleven inches in diameter and about three inches in height.

lt will be observed that the hood curves upwardly and inwardly and then down llO wardly and inwardly, so thatthe inner por- I outer edge thereof and a trough between tion of the hood-is substantially parallel with I said openings; a hoodadapted to rest-upon the walls of the outer portion of the trough of the bed plate, thereby permitting the air to pass upwardly and then downwardly betweenthe hood and the bedplate and thon out between the hood and the spreader. The spreader-and hood are held in place'by theirivowuweight. The'oil supply pipe is furnished'lby"suitableregulating means, not Y' showpgio jintrolft'he flow of the fuel. ln f "startingasv sin'all amount of .oil would be pel'lnittedftofti'ow .into the trough in the bed i '-plate. `T -Th'ifs 'eouldlbe ignited by, a torch or "Z1-5" liglitedjinany other .suitable manner. The burnin'ggof the oilsoon heats lthe hood and 'the sproa'd'ei.'l aid 'thereafter asmall continuous 'fiow of,`oil is'perniitted from the supplypipegf- Qlhsgvaporizes.upon the bed 2O plateandthe air -coining throuvh the draft `openings unites therewith and'i'orins a com- I' bustibl'e gas'f'whieh burns in a flame 'around 'the lspreader," keeping the sainel red hot. Shouldaiiyresiduuin' bedeposited on the 2:5 plate the-.spreader and hood can easily i "beu'emoyed' and suoli residuuni taken off the' bed plate 'in any 'suitable manner. As the Haine burns'over the top of the hood the sainebee'omes very hotand the air-passing through the draft openinfs of the bed plate Y strikes this hot surface and is deflected downwardly into the ascending vapor as it rises off the bed plate, thereby causing an intimate i mixture of the air an oil vapor before it passes out from betweenl the spreader and hood, thus making a perfect gas which .burns readily and Without soot.

By this construction a simple and elioient Vburner is provided of detachable parts which. '4'O can be easily replaced when burned outl and which can be quickly and e. ily cleaned and keptfin order.

Having described iny invention. what l claim is:--A

1. A hydro-carbon burner comprising a bed` plate having draft openings near the said bed plate and having a draft opening 1n the center thereof, said hood `curving upwardly and lnwardly and then downwardly and inwardly; a liquid fuel supply pipeprojeoting throu l1 the eenter of said A bed plate; and a sprea er having legsadapt'- ed to rest upon the bed plate,`sa1d spreader curving upwardly and out-wardl7 and pro- 'jeeling above theinner part of the hood.

2. A hydro-carbon burner comprising a bed plate and a detachable hood, the bed plate having air ports in the outer portion of which slope from the bottom o the trough in both directions; a hood adapted to rest upon said bed plate having a. draft opening in the center thereof, said hood having its 'walls sloping upwardly and inwardly and then inwardly'and downwardly; a spreader llnwing legs adaptedto rest upon the eentral portion of the bed plate and having the body thereof slopingl upwardlyv and outwardly and projecting'above the inner part of the hood; and a supporting ring below said bed plate.

lin witness that I claim the foregoing I have hereunto subscribed my name this 29th day of March, 1909.
